Discussion

Subspecies versicolor is critically imperiled in British Columbia, threatened by development pressure, habitat alteration, and competition from introduced species. The Canadian populations are over 400 km north of the nearest United States populations, in Oregon. This disjunction may be a result of the discontinuity of available habitat, introduction since glaciation, or survival of populations in glacial refugia (J. L. Penny and G. W. Douglas 1999).
